ISS Finally completed in 2010 after a torturous 25-year development and production process, the International Space Station was originally conceived as the staging post for manned exploration of the solar systrem. Instead, it was seemed to be the death knell of manned spaceflight. More...

Progress thrusters (DPO) were inhibited and not involved. (Crew activities focused on TORU activation, inputting commands via the RUO Rotational Hand Controller and close-out ops. TORU lets an SM-based crewmember perform the approach and docking of automated Progress vehicles in case of failure of the automated KURS system. Receiving a video image of the approaching ISS, as seen from a Progress-mounted docking television camera ('Klest'), on a color monitor ('Simvol-Ts', i.e. 'symbol center') which also displays an overlay of rendezvous data from the onboard digital computer, the crewmember steers the Progress to mechanical contact by means of two hand controllers, one for rotation (RUO), the other for translation (RUD), on adjustable armrests. The controller-generated commands are transmitted from the SM's TORU control panel to the Progress via VHF radio. In addition to the Simvol-Ts color monitor, range, range rate (approach velocity) and relative angular position data are displayed on the 'Klest-M' video monitor (VKU) which starts picking up signals from Progress when it is still approximately 7 km away. TORU is monitored in real time from TsUP over Russian ground sites (RGS) and via Ku-band from Houston, but its control cannot be taken over from the ground.) Additional Details: here....

(Today's troubleshooting dealt with repair and cleaning of a threaded hole on a standoff element for the right K-BAR capture fitting. The FE-2 used a vacuum cleaner to remove FOD (Foreign Object Debris) plus safety goggles, rubber gloves and a surgical mask for his protection.)

(SONOKARD objectives are stated to (1) study the feasibility of obtaining the maximum of data through computer processing of records obtained overnight, (2) systematically record the crewmember's physiological functions during sleep, (3) study the feasibility of obtaining real-time crew health data. Investigators believe that contactless acquisition of cardiorespiratory data over the night period could serve as a basis for developing efficient criteria for evaluating and predicting adaptive capability of human body in long-duration space flight.)

STS-123/Endeavour (ISS-1J/A) lifted off spectacularly in darkness early this morning right on time (2:28am EDT) with all systems performing nominally, for rendezvous with ISS tomorrow (3/12, Wednesday) and docking at approximately 11:25pm EDT. The Orbiter is carrying the seven-member crew of Commander Dominic L. Gorie, Pilot Gregory H. Johnson and Mission Specialists Richard M. Linnehan, Robert L. Behnken, Michael J. Foreman, Takao Doi and Garrett E. Reisman. Reisman will replace LĂ(c)opold Eyharts as ISS Flight Engineer 2, who returns on 3/26 (nominal) with STS-123. STS-123 is the 122nd space shuttle flight, the 21st flight for Endeavour, the 25th flight to the station and the second of six Shuttle flights planned for 2008 (including the Hubble Service Mission 4). Its primary payloads are the 18,490-lbs Japanese Experiment Logistics Module-Pressurized Section (ELM-PS or JLP) and the 3,400-lbs Canadian Special Purpose Dexterous Manipulator (SPDM) 'Dextre'. We are off to another great mission! Additional Details: here....

Prepared the JAXA JLP (JEM Experiment Logistics Module Pressurized Section) for its transfer, i.e. - opened and secured the protective flap over the Node-2 topside (zenith) hatch viewport for the internal CBCS (Centerline Berthing Camera System), removed 8 PCBM (Passive Common Berthing Mechanism) contamination protection covers, demated & stowed JLP LTA (Launch-to-Activation) connectors & installed protective caps on the LTA receptacles; Performed Part 1 Assembly of the SPDM (Special Purpose Dexterous Manipulator), i.e. - released two OTCMs (ORU Tool Changeout Mechanisms) from the launch locations on the SLP (Spacelab Pallet), installed the OTCMs on the SPDM, released the OTP EDFs (ORU Temporary Platform Expandable Diameter Fasteners), inspected the SLP PDGF (Power & Data Grapple Fixture) horseshoe connectors; Took photographs of the SPDM, and Installed a protective wire tie over the sharp edge divot discovered during Flight 1A on the Airlock (A/L) handrail. Official start time of the spacewalk was 9:18pm EDT, about 5 min ahead of timeline, and it ended at 4:19am. Total EVA duration (PET = Phase Elapsed Time) was 7h 1min. It was the 105th spacewalk for ISS assembly & maintenance and the 77th from the station (55 from Quest, 22 from Pirs, 28 from Shuttle) totaling 472h 22min, and the 9th for Expedition 16 (totaling 64h 30min) and the 6th so far this year. After today's EVA, a total of 131 spacewalkers (99 NASA astronauts, 21 Russians, and 11 astronauts representing Japan-1, Canada-4, France-1, Germany-2 and Sweden-3) have logged a total of 660h 44min outside the station on building, outfitting and servicing. It was also the 127th spacewalk involving U.S. astronauts.) Additional Details: here....

SPDM Dextre was checked out and is working nominally with both arms. (The waist-up-only robot from Canada arrived in space in nine separate pieces that are being assembled in the current spacewalks. Each of the two arms has seven joints; in addition, SPDM (Special Purpose Dexterous Manipulator) Dextre can pivot at the 'waist'. Its grippers (hands) have built-in socket wrenches, cameras & lights. Only one arm is movable at a time, to keep the robot stable and avoid a two-arm collision. Dextre can be attached to MT (Mobile Transporter) to translate along the stations rail tracks, or alternately to the SSRMS (Space Station Remote Manipulator System) to swing to places where the railcart can't go. What a supercool helper!) Additional Details: here....

After wake-up yesterday at ~3:30pm, CDR Peggy Whitson completed another session with the SLEEP experiment (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop for downlink, as suggested on her discretionary 'job jar' task list. (To monitor the crewmember's sleep/wake patterns and light exposure, Peggy wears a special Actiwatch device which measures the light levels encountered by him as well as his patterns of sleep and activity throughout the Expedition. The log entries are done within 15 minutes of final awakening for seven consecutive days, as part of the crew's discretionary 'job jar' task list.) Additional Details: here....

SPDM (Special Purpose Dexterous Manipulator) 'Dextre', with repositioned arms, was successfully stowed on the U.S. Lab PDGF (Power & Data Grapple Fixture) (and is looking very cool); SLP (Spacelab Pallet) was returned to the Shuttle PLB (Payload Bay) for re-berthing; and SSRMS (Space Station Remote Manipulator System) was 'walked off' the Node-2 PDGF onto MT/MBS (Mobile Transporter/Mobile Base System) PDGF-3 and maneuvered into position for today's MT translation from Worksite 6 (WS6) to WS4. (During commanding of the SPDM's body ('waist') roll joint to stowage mode, it rotated in the opposite direction than expected, due to a sign mistake (polarity inversion, i.e., a plus-sign instead of a minus-sign) in the DMCS (Dexterous Manipulator Control Software) configuration file. Flight Controllers worked around this in real time, and the crew was able to maneuver the SPDM LEE (Latching End Effector) onto the LAB PDGF without further ado. Work is underway at CSA/MDA to write a corrective software patch.) Additional Details: here....

After wakeup yesterday at ~1:30pm EDT and before breakfast, CDR Peggy Whitson completed another session with the SLEEP (Sleep-Wake Actigraphy & Light Exposure during Spaceflight) experiment software for data logging and filling in questionnaire entries in the experiment's laptop session file on the HRF-1 laptop, as suggested on her discretionary 'job jar' task list.

Demonstrated an on-orbit heat shield repair technique using the T-RAD (Tile Repair Ablator Dispenser) to demonstrate an Orbiter tile repair DTO (Development Test Objective) in space. (The spacewalkers tested STA-54, a pink putty-like material consisting of two compounds that are mixed together in a pressure-driven applicator gun just before they exit the nozzle. With Foreman working the applicator, the test was completed nominally, and the test samples were stowed in the TSA (Tool Stowage Assembly in the Orbiter PLB (Payload Bay) for return and analysis; results looked good); Removed RPCM (Remote Power Controller Module) S02B-D on the S0 truss and replaced it with a new unit. (Since the RPCM controls CMG-2 (Control Moment Gyroscope #2), circuitry had to be powered down and the CMG-2 removed from the steering law beforehand. After the successful R&R, the spacewalkers attempted several times to reconfigure the Z1 patch panel, a pre-requisite for powering the new RPCM, but were unable to do so due to tough-to-reach connectors which could not be unmated. The patch panel reconfiguration currently remains incomplete, but there are no impacts to current operations); Inspected the Z1 truss toolbox for MMOD (Micrometeoroid/Orbital Debris) damage and noticed several 'pits'. (Video imagery will be assessed by specialists); Released Node-2 Port ACBM (Active Common Berthing Mechanism) launch locks in preparation for berthing the JEM (Japanese Experiment Module) module 'Kibo' on Flight 1J next May; Removed the remaining SPDM OTCM-2 (Special Purpose Dexterous Manipulator/ORU Tool Changeout Mechanism #2) thermal covers, reconfigured some of the wrist blankets and flaps, and inspected the Shoulder Roll joint of SPDM Arm #2 for possible MLI (Multi-Layered Insulation) interference. None was seen. (WVS (Wireless Video System) helmet cam video was also obtained for ground analysis.) Additionally, two get-ahead tasks were completed: Additional Details: here....

Ahead: Week 23 of Increment 16. HAPPY EASTER! Congratulations, Shuttle & ISS crews: Five EVAs in a row, all successful. What a great Easter gift!

>>>>Today at ~7:43am EDT, the ISS, specifically its FGB module, completed 53,500 orbits of the Earth, having covered a distance of 2.25 billion kilometers (1.4 billion st.miles) in 3411 days. The 19,300 kg (42,600 lbs) Zarya ('Dawn') was launched on a Russian/Khrunichev Proton from Baikonur over nine years ago (11/20/1998) as the first element of the multi-national space station.<<<< Additional Details: here....
